Disclosed is an authentication device. The authentication device comprises: a storage unit for storing authentication information and a plurality of counting information corresponding to a conversion method for converting the authentication information into a sound wave signal; a control unit for converting the authentication information into a sound wave signal by a conversion method corresponding to the counting information changed according to the number of user input; and a sound wave output unit for outputting the authentication information converted into the sound wave signal and the changed counting information as a sound wave signal. Accordingly, it is possible to achieve the effect of improving security as the sound wave signal for transmitting the same authentication information is changed according to the counting information.

Authentication device and control method thereof

A device for transmitting authentication information is disclosed. The device for transmitting authentication information according to an embodiment of the present invention comprises: a housing in which a predetermined space is formed; an acoustic output part which is partially exposed outside the housing, is pushed a predetermined distance backward when pressed by an external force, moves forward and returns to the original position in the state where the external force is released, and when pushed backward, outputs authentication information converted into an acoustic signal; and a substrate having a plurality of acoustic output part-coupling holes to which the acoustic output part is coupled movably back and forth.

Device for transmitting authentication information

A display device includes: a base substrate; a first pixel electrode, a second pixel electrode, and a third pixel electrode arranged on the base substrate to be spaced apart from each other; a pixel defining film on the first pixel electrode, the second pixel electrode, and the third pixel electrode and including a first opening exposing the first pixel electrode, a second opening exposing the second pixel electrode and spaced apart from the first opening, and a third opening exposing the third pixel electrode and spaced apart from the first opening and the second opening; a first organic layer on the first pixel electrode exposed by the first opening; a second organic layer on the second pixel electrode exposed by the second opening; and a third organic layer on the third pixel electrode exposed by the third opening.

Display device including a plurality of layers each including a light emitting layer

Provided are a die pickup module and a die bonding apparatus including the same. The die pickup module includes a wafer stage for supporting a wafer including dies attached on a dicing tape, a die ejector arranged under the dicing tape and for separating a die to be picked up from the dicing tape, a non-contact picker for picking up the die in a non-contact manner so as not to contact a front surface of the die, a vertical driving unit for moving the non-contact picker in a vertical direction to pick up the die and an inverting driving unit for inverting the non-contact picker to invert a die picked up by the non-contact picker.

Display device including a plurality of layers each including a light emitting layer and having an island shape

An induction heating cooking device includes a cooking table having an auxiliary slit; an induction coil for generating a magnetic field so as to inductively heat a cooking container placed on the cooking table; multiple light sources disposed at the outside of the induction coil; and a main slit through which light emitted from the light sources passes. The induction heating cooking device forms a virtual flame image on the cooking container, thereby enabling the heating state of the induction heating cooking device to be intuitively checked.

Induction heating cooking device

A device for transmitting authentication information is disclosed. A device for transmitting authentication information, according to one embodiment of the present invention, comprises: a storage unit for storing authentication information and frequency information corresponding to letters or numbers included in the authentication information; a control unit for generating sound wave signals having a frequency corresponding to the letters or numbers included in the authentication information; and a sound wave output unit for outputting the sound wave signal, wherein the control unit sequentially generates, in the order in which the letters or numbers are enumerated, sound wave signals having a frequency corresponding to the letters or numbers included in the authentication information, and repeatedly generates, a preset number of times, a sound wave signal having a frequency corresponding to each letter or number.

Device for transmitting authentication information by using ultrasonic waves

A user authentication method using ultrasonic waves is disclosed. The user authentication method using ultrasonic waves, according to an embodiment of the present invention, comprises the steps of: receiving a sound wave signal which includes analog data; sampling the sound wave signal at a preset sampling rate; generating a block by selecting a preset number of pieces of sampling data; converting sampled data included in the block into frequency components; and determining, as digital data in the block, a letter or number corresponding to the frequency component having the largest magnitude from among the frequency components.

User authentication method using ultrasonic waves

Disclosed is an authentication apparatus. The authentication apparatus according to an embodiment of the present invention comprises: a storage unit for storing authentication data corresponding to content stored in a management server; a control unit for converting the authentication data into a sound wave signal; and a sound wave output unit for outputting the converted sound wave signal.

Contactless user authentication method

A user equipment is provided. The user equipment includes a user interface, a transceiver and a processor. The user interface may receive an input of a food model including at least one of a shape, an ingredient, or a color of a food in accordance with a touch input of a user. The transceiver may transmit information of the food model to a cooking apparatus capable of shaping and heating the food. The processor may transmit the information of the food model to the cooking apparatus via the transceiver to allow the cooking apparatus to shape the food according to the food model. Further, the user interface may display an automatic cooking button, a draw button, a cooking method button, and an output button.

User equipment configured to transmit a food model to a cooking apparatus

A cooking system is provided. The cooking system includes a user equipment and one or more cooking apparatuses. The user equipment may include a user interface configured to receive an input of a food model including at least one of a shape, an ingredient, or a color of a food in accordance with a touch input of a user, a first transceiver configured to transmit information on the food model to the one or more cooking apparatuses, and a first processor configured to transmit information of the food model to the plurality of cooking apparatuses via the first transceiver. Each of the one or more cooking apparatuses may include a second transceiver configured to receive information on the food model from the user equipment, a food shaping device configured to discharge food ingredients, a food heating device, and a second processor.
